Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic mooring device for mooring a ship to a quay or other vessel. When mooring a ship, the following steps are taken: 0 ■ Two or three people are placed at the bow and stern, and a person in charge of mooring is placed in the wheelhouse in the center of the ship, and the mooring is attempted. When approaching the other party's vessel (or quay), first throw a thin rope tied to the tip of the mooring line (wire rope, etc.) to the other party from the bow side.

■On the other ship's ship, the worker pulls this rope to bring the mooring line together, and ties this mooring line to the own ship's bit (or bollard).

■ Wind up a predetermined amount of the mooring line with a mooring winch to complete the work on the bow side.

■Similar work is carried out on the stern section, completing the series of mooring work (if the ship becomes large, the center section is also moored with mooring lines in addition to the bow and stern).

[Problem that the invention seeks to solve]

However, such conventional mooring work requires a lot of manpower and time, and the wire rope chopsticks normally used as mooring ropes can cause breakage accidents.
The problem is that the mooring work itself is extremely dangerous.

The present invention was made in view of these problems, and it is an object of the present invention to provide an automatic mooring device that can safely and appropriately moor a ship with less manpower.

[Elaborate means to solve problems]

Finally, the present invention is equipped with an extendable arm that can extend and contract from the hull to a quay or other vessel, and a mooring device that can be moored to a bit or bollard installed on the quay or other vessel at the tip of the extendable arm. establish. This telescoping arm is installed on a self-propelled carriage along the longitudinal direction of the ship's side so that it can move in the longitudinal direction of the ship's side.

Furthermore, the telescoping arm can be horizontally pivoted on the carriage and is mounted so as to be able to move up and down.

[For production]

A telescoping arm with a mooring device that extends from the hull and can be moored to a quay or other vessel is made to move along the longitudinal direction of the ship's side of the carriage, and is attached to a mooring bit on the quay or other vessel.
Stop the vehicle near a designated area. From there, the telescoping arm is appropriately extended/contracted, raised/raised, and horizontally rotated to hook the mooring tool onto a mooring bit, etc., and then the telescoping arm is retracted to apply necessary tension to moor the ship.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show an embodiment of the invention, which comprises a carriage (1), a telescoping arm (2) and a tether (3). In this example, the carriage (1) is the upper row ridge (1).
A) and a lower carriage (1b) are used.As shown in the drawing, a recess is provided in the longitudinal direction of the ship's hull (10), and a T-shape parallel to each other is provided in the longitudinal direction of the ship's hull (10). The two carriages (1&) (lb) installed on the upper guide rail (101) and lower guide rail # (102) of the mold are installed on the upper guide rail (101) or the lower guide rail (102) as shown in Figure 3. The carriage main body αG installed so as to surround the lower guide rail (102) and the rail (100 or (1
Wheel α in contact with the top surface of the rail body (103) of 02)
and the wheel (IIIL) (llb
), and the rail abdomen (104) is provided between both sides f.
It is composed of nine horizontal rollers (12) (12&). The wheels (11) (lla) (1b) support the load in the vertical direction, and the horizontal rollers (12) (1b)
2a) prevents vibration and displacement in the left-right direction, and the above-described configuration allows both carriages (la) and (lb) to run stably on the guide rail (101) or (102). In addition, a rack (105) is fixed in the longitudinal direction on the side of the rail body (103) of the lower guide rail (102), and a binion gear αJ that engages this rack (105) is attached to the carriage body αG. By rotating it with the drive source CI4, the lower stage carriage (1b) is made to run along the lower stage guide rail (102). Furthermore, as shown in FIG. 4, the rail body (103) of the lower guide rail (102)
A pinhole (%-(106)) is provided at each location, and the lock pin 4 fitted therein can be inserted or removed by pushing out or pulling it out with a lock cylinder M fixed to the carriage body. , the lower carriage (1b) can be fixed at a predetermined position.

Furthermore, since the telescoping arm (2) installed on the lower carriage (1b) is connected to the elevation cylinder (described later) extending from the upper carriage (1b), the upper carriage (1b)
a) moves with the travel of the lower carriage (1b).

The telescopic arm (2) is composed of a hydraulic cylinder, and the base end of the cylinder body is attached to a vertical eye (E) so that it can be raised and raised freely.
One end of this vertical eye is further attached to a lower carriage (lb) so that it can rotate horizontally. The upper carriage (lb) is fixed to the lower carriage (lb), and is attached to the lower carriage (lb) so as to be able to rotate horizontally and vertically. 1a) is provided with an elevating cylinder (E), and its cylinder hood (23a) is attached to the arm eye fixed to the main body of the retractable arm (2) to extend and retract the elevating cylinder. The arm (2) is designed to be able to look down. Also, the rod (
25a) is a rotating cylinder (a) that expands and contracts in the horizontal direction.
Fix the base end on the lower carriage (1b)]
, connect this rod (25 m) to the horizontal eye Cη,
1Ifl by expanding and contracting the rotating cylinder (c)
The telescoping arm (2) is designed to be able to pivot in the horizontal direction on the lower carriage (1b) about the horizontal eye Qη.

Mooring device (3) F'S, more than the mooring rope attached to the tip of the rod (2a) of the extension/retraction arm (2),
It is installed on a quay or other vessel and is used by hooking it to a safety mooring bit or bollard. As this mooring device (3), any mooring device such as a mooring eye or a mooring bit can be used in addition to a mooring rope.In addition, in this embodiment, a control stand with a TV camera (110 ) is installed, and the various mooring operations performed by this device are transmitted as images into the cabin through which the operations of each device are controlled. ) and the hydraulic pressure of the swing cylinder 4 are supplied from the hull through a hose, and when mooring, the telescopic arm (2) applies appropriate tension to the mooring device (3). The amount is automatically adjusted.

This device having the above structure is operated as follows. First, when the hull (100) approaches the quay (120) or the hull of another vessel (120a) and stops, the lower carriage (1b) is self-propelled together with the upper carriage (l&), and the Stop near the mooring bit (121) of the lower guide rail (102) and insert the lock bin 4 into the pinhole (106) of the lower guide rail (102) to fix it. Then, as shown in Fig. 2, the telescoping arm (2) is rotated in the horizontal direction by the rotation cylinder (E), and the telescoping arm (2) is moored (1).
21) Adjust the angle of elevation of the telescopic arm (2) according to the installation height of the mooring bit (121) using the elevation cylinder as shown in FIG. While extending the rod (2a) of the telescoping arm (2), move the telescoping arm (2) up and down a little to hook the mooring tool (3) at the tip of the rod (2a) to the mooring bit (121). Finally, shorten the rod (2a) a little and make the mooring bit (121
) Apply appropriate tension to the hooked mooring device (3) to complete the mooring.

Also, the telescoping arm (2) is removed by following the procedure reverse to the above procedure for releasing the mooring, and finally the telescoping arm (2) is stored in the recess (iooa) using the swing cylinder 4.

〔Effect of the invention〕

According to the present invention described above, the mooring work, which conventionally relied on human hands, can be performed in a short time by mechanical operation, and has the effect of streamlining the work and ensuring safety.
